Seasonic have recently released a new range of power supplies targeting the mainstream audience. There are four supplies in this new range of Gold certified units (650W, 750W, 850W and 1000W), and today we look at the 850W model. These Core GX 80 Plus Gold power supplies are fully modular and are ATX 3/PCIe5 compliant.

In the words of Seasonic these units are ‘catering to a broad spectrum of PC enthusiasts and system builders'. Following the newest trends in graphics card design, the units in this family comply with the latest ATX 3.1 and PCIe GEN 5.1 standards'.

Seasonic are also planning on releasing white versions of these units and according to literature we received from the company the white versions will be released in Europe late February. North America release dates are January 2025 for black colour and ‘Build to order only' for white colour. They also say stock availability may vary depending on each country.

These power supplies are positioned as a mid tier unit in the Seasonic range with a 7 year warranty, below the Prime (12 year warranty) and Focus (10 year warranty) power supplies and above the G12 and B12 (both 5 year warranty).
